Warhead influence

摘要

An active electromagnetic influence firing system has transmitter coils and receiver coils mounted on a single warhead section. One set of receiver coils has vertical look capability for detecting surface ships and another set has 360 DEG look capability for detecting submarines. An influence electronics package automatically nulls out directly induced electromagnetic radiation and passes only the signature received from targets. Amplitude, duration, and frequency criteria implemented by circuitry in the influence electronics package determine whether there is a valid target.
